Aphids. Macrophotograph of unidentified aphids on a plant stem. Aphids are small insects that feed on plant juices,and are a major agricultural pest. Aphids can rapidly establish huge populations,as they are able to reproduce without the need for fertilisation (parthenogenesis),and can produce live young. Insecticides can be used to control their numbers,but biological control using ladybirds,a natural predator of aphids,is often used also | |
